Consider the online median problem: we are given a stream of integers $($for simplicity assume that they are all distinct$).$ On reading the nth input integer, we are required to quickly output the median of all the n integers we have seen so far $($the median of a set of n numbers when n is odd is uniquely defined; you may define what the median of a set of n integers $\{$x$1,$ x$2,...,$ xn$\}$ is when n is even, but explicitly state the definition in your answer$).$ Design and analyze an efficient algorithm that can compute the me$.$ explain the algorithm as well.
